In the course of the investigation of cholesterol he found the dehydrogenation with Selenium. In 1928 together with Kurt Alder he developed a method of preparing cyclic organic compounds (Diels-Alder reaction) and the pair were jointly awarded the 1950 Nobel Prize for chemistry.

Extractions: In 1927 Diels dehydrogenated cholesterol to produce 'Diels hydrocarbon' (C18H16), an aromatic hydrocarbon closely related to the skeletal structure of all steroids, of which cholesterol is one. In 1935 he synthesized it. This work proved to be a turning point in the understanding of the chemistry of cholesterol and other steroids. Working with his assistant Alder, Diels developed the diene synthesis, which first achieved success in 1928, when they combined cyclopentadiene with maleic anhydride (cis-butenedioic anhydride) to form a complex derivative of phthalic anhydride. Generally, conjugated dienes (compounds with two double bonds separated by a single bond) react with dienophiles (compounds with one double bond activated by a neighbouring substituent such as a carbonyl or carboxyl group) to form a six-membered ring.

Extractions: Encyclopædia Universalis, le portail de la connaissance Accueil Boutique Contact Assistance J'ai oublié mon mot de passe Zone de recherche Saisir un mot clef Chimiste allemand né à Hambourg, décédé à Kiel. Diels soutient en 1899 sa thèse de doctorat préparée à l'université de Berlin où il reste en poste jusqu'en 1916 : assistant dès 1899, il y est maître de conférences en 1904, directeur du département de chimie en 1913 et professeur associé en 1914. En 1916, il est nommé professeur et directeur de l'Institut de chimie à Kiel, postes qu'il va occuper jusqu'à son départ en retraite en 1948. En 1906, Diels obtient le suboxyde de carbone (C O ), dont il étudie les propriétés. Il s'intéresse ensuite à la détermination de la structure du cholestérol dont il obtient par déshydrogénation, à l'aide du sélénium, un hydrocarbure auquel on donnera le nom de « hydrocarbure de Diels » ; ce travail sera important pour la détermination finale de la structure du cholestérol effectuée en 1932 par d'autres équipes.
